PUMP.

SPECIFICATION forming part of Letters Patent N o. 403,507', dated May21, 1889.

Application filed July 13, 1888. Serial No. 279,827. (No model.)

T0 (Ll/Z 'wiz/0711, it may concern:

Be it known that I, PETER J. BODE, a citizen of the United States,residing at Belleville, in the county of St. Clair, State of Illinois7have invented a new and useful Improvement in Pumps, which improvementis fully set forth in the following specification and accompanyingdrawings.

My invention relates to improvements in pumps; and it consists of meansfor automatically draining the pump to guard against freezing.

It also consists of means for readily changing the pump from a liftingand force pump to a sand-pump.

It also consists of other novel and advantageous features, as will behereinafter set forth.

Figure 1 represents a vertical section of a pump embodying my invention.Fig. 2 represents a perspective view of a detached portion thereof. Fig.3 represents a side elevation of the stand. Fig. et represents avertical section of a portion on an enlarged scale. Fig. 5 represents atop view of one of the valves.

Similar letters and numerals of reference indicate corresponding partsin the several figures.

Referring to the drawings, A represents the plunger or pump-rod, whichhas at its upper end a rack, 1,with which meshes asegment, 2, formingpart of the pump-handle, common to hand-pumps. The extreme upper end ofthe rack 1 has a hook or eye, 3, or similar device, whereby it can bereadily connected with the operating-stein of a windmill or other powerfor impart-ing power to the rod A. Then I employ such power, Iremove thesegment 2 and handle, and slip in their place a casting, B. (Shown inFig. 2.) This piece is provided with openings 4. to receive the boltholding the segment in place, and forms an angular box, in which therack is properly and truly guided. The rack 1 is secured at its lowerend to the rod proper bymeans of a set-screw, 5. The arm 6, whichcarries the segment and handle, is provided with an annulus, 7, whichencircles the upper end of the air-chamber O, and is held in place bythe set-screw 8, permitting the handle to be located in any desireddirection.

Cast with or otherwise secured to said annulus is a brace or support, 9,which assists in securing the plunger-guide and strengthening the upperstructure. A cover, 10, is employed at top for preventing foreign matterreaching the rack and pinion, as well as guarding against accidents.

The air-chamber O is provided at its upper end with a stuffing-box, 11,common in pumps, and rests on stands, 12, which are secured thereto inany proper manner, and formed of parts which may be readily removed forrepairs, &c., and easily cast, handled, and packed, also securing astrong, durable, and attractive structure.

D represents the pipe of the pump connecting the air-chamber O with thepump proper, and having at its'base an offset or d rainin g-valvechamber, 13, the same bein g on the upper pump-casin g 14 and preferablycast therewith, said chamber also serving as a trap for catching pins,pebbles, dac., that may be thrown into the pump from above. A cap ortop, 15, is secured to the drainage-valve chamber 13 in any suitablemanner and receives the pipe D of the pump. On one side of said cap isan opening, 16, which receives the stem of the drainage-valve 17 andguides the same. The valve is provided on its upper side with packing1S, and has its seat on the opening 19 in the upper wall of thepump-casing 14, as well as at the base of the opening 16.

Between the upper pump-casing, 11, and lower pump-casing, 20, is clampeda flexible diaphragm, 21, the two casings being properly connected bybolts or otherwise. This diaphragm 21 has an opening in its center toreceive the seat of the valve 22 of the pump, constructed as follows: Acasting, 23, is passed through the opening in the diaphragm and heldsecurely in place by a casting, 24, these two castings or pieces iiaringin opposite directions to allow the diaphragm to roll thereon when thepump is operated. Screwed or otherwise secured to the top of the piece23 is a perforated cap or cup-shaped piece, 25, which acts as a guide tothe valve 22, and has connected with it the lower end of the pumprod A,which latter has a-screw-thread on its lower end, which end is adaptedto pass through an opening in the cap 25 and bear against the valve 22,so as to force the same IOO against its seat on the piece By thisconstruction I provide means for guiding the valve without fittings atthe top, an essential feature, as no obstructions are offered to theWater in its upward passage, leaving the dis,- charge-opening in thepiece 23 fully open.

The lower part, 20, of the pump-chamber has on its side a cylindrical orother shaped proj ection, 26, leaving an opening, whichforms avalve-seat for a valve,27. This valve is inclosed by a spout, 28,properly secured to the pumpchamber 20 and carrying a thumb-screw, 29,which bears against the valve 27. The bottom of the lower pump-casting2O is inclined or sloping, as shown in Fig. 1, the purpose of which isto cause the sand which enters said casting to slide out easily throughthe discharge or vexit openin g 26. A great advantage is thus obtainedin sloping the wall of said casting, for if the wall were straight thesand would not slide out through the dischargeopening, but would iillthe chamber of the pump and prevent the operation of the same.

Centrally located at the lower end of the pump-chamber 20 is thesuction-pipe 30, and rising vabove the base thereof is a projection, 31,on which is seated the lower valve, 32, held in place by a perforatedyoke or box, 33, secured to said projection, the yoke serving as a guidefor the valve 32.

It will be seen that the handle and segment operate the rod A, andconsequently the diaphragm 21. The valve 27 is tightly closed, and it isevident that whatever Water or fiuid may be at the lower end of thesuction-pipe 30 will be drawn into the pump-chamber and dischargedthrough the valve 22, reaching the air-chamber, and discharging fromthenozzle or spout 34 of the pump. The pressure above the diaphragm 21will raise the valve 17 and close theV opening 16, thus preventingdischarge therethrough. When the pumping ceases, said valve 17 falls,thus opening the passage or opening 16 and allowing the pump to drainautomatically.

Should it become necessary to pump sand, as in driven wells, theset-screw 5 is loosened and the pump-rod A turned until it screws downon the valve 22 and closes the same tightly on the, piece 23. Theset-'screw 29 is now withdrawn the required distance and j the pump maybe operated, the pump-rod A having been again connected with the rack lby the set-screw 5. It will be seen that I thus discharge all sand andforeign matter through the spout 28, and thus prevent the objectionablematter froin coming upon the pump. NVhen the flow through the spout issuch as to resume pumping through the spout 34, the valve 27 is closedby the set-screw 29 and the valve 22 is opened, and usual pumping may beproceeded with.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a pump, the combination of the pumpchamber, the perforated capabove the inlet thereof, the lower or foot valve arranged in said cap,the outlet having a hinged valve or cover, the screw for closing saidvalve-cover, the diaphragm in the pump-chamber carrying the perforatedcap, the valve therein, and the plunger-rod having its lower end screwedinto the cap and adapted to be screwed down on the valve, arranged andoperating substantially in the manner and for the purpose described.

2. In a pump, the combination, with the pump-chamber havin gthediaphragm therein, the valve carried by said diaphragm,the perforatedcap in which said valve is arranged, the piston-rod having its lower endconnected to said cap, the supply-pipe, and air-chamber, of the topbracket having a cover for the operating mechanism, and an annulus orcollar embracing the top of the air-chamber,where by said bracket may berotated on the airchamber to place the operating mechanism in aconvenient position and may cause the plunger-rod to close the valve ofthe diaphragm or adjust the play of the same as desired, substantiallyas and for the purpose described.

3. In a pump, the pump-chamber provided with a foot-valve above theinlet thereof, having its lower wall inclined and an outlet at thetermination of said wall, a hinged valve controlling said outlet, ascrew for regulating the play of the valve or for closing the same onits seat, a diaphragm in the pumpchamber, a perforated cap carried bysaid diaphragm, a valve arranged in and guided by said cap, and aplunger-rod having its iower end adjustable in said cap, whereby theplay of the valve may be regulated or the same closed on its seat,substantially in the manner and for the purpose described.

4. A pump having a chamber with a footvalve controlling itsinlet-passage, a hinged valve controlling its outlet-passage, a spoutsurrounding its outlet-passage and having a screw regulating the play ofthe said hinged valve, and a diaphragm in said chamber withoperating-stem, said parts being combined substantially as and for thepurpose set forth.
